[#13] the Devices tab is now visible to all projects, not only those generated by GNU ARM Eclipse.

Addressed bugs

[SF bugs#195] the content of the Toolchains tab was not updated when the build configuration changed; fixed.

Template issues

the CMSIS Core was updated to v4.4;

the STM32F4 HAL was updated to v1.9.0;

the implementation of assert_failed() was made weak, to allow redefinitions.

Other changes

part of the µOS++ III code used by the templates (ARM Core, STM32F4 CMSIS, STM32F4 HAL) was migrated to separate packages, available in the GitHub project xPacks. Eventually the entire dependency on µOS++ III will be migrated to separate packages.
